Redbrick's 850 made 370bhp with the 2.5, 19t and supporting mods on a Maha dyno. I believe the highest bhp seen on the same dyno with a k24 was around 10bhp less on an S60R with a flowed head/WI/etc. Not that peak HP really says what is what. If you were to drive Redbricks or my 850 you would find it is anything but laggy, it's savage, from any gear at any revs. 60-100 times about 1 second quicker than my old S70 with a new K24, and that was heavily modified too.
Why ask questions you know the answer to? You know that my S60 made three thirty something on the dyno day. And you know that it has been remapped since then. On that day, the car was running an MTE stage 2 remap for a K24, and when it went on the dyno, the boost was pulsing up and down (for some unknown reason, it's not something that happened on the road). I agree, and if you wanted to put a figure on the car, I would expect a peak figure of around 350bhp. At some stage I'll get it on a random number generator to put your mind at rest.
Second hand K24's are a waste of time. At factory boost they cope ok, but as soon as you up the boost they become a ticking time bomb. How many people who use a K24 on their car use their car on track? And I don't mean a 15 second blast up a drag strip, or one or two teaser track sessions, or one full track day a year, I mean actually use their car in anger on a track several times a year? I can only think of one, Ashok on T5D5. Ask him how many new K24's he has gone through. A new one will last a while, but I wouldn't waste my money.
If you want reliability and longevity, fit a brand new standard 19t. And you should get a good few years of track abuse out of it.
